AIR DISTRIBUTOR.

Application filed July 29, 1925.

My invention relates to new and useful improvements in an air distributor, and more particularly to a device of this character for use in connection with oil heaters and stoves, gas stoves and other devices having an open flame, and has for its object to provide an arrangement of elements whereby the combustion is improved, the flame will be odorless and smokeless, and where used for lighting purposes the brilliancy of the flame will be intensified.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. 1, is a fragmentary plan view of an oil heater with the heating drum removed showing my improvement connected therewith.

Fig. 2, is a fragmentary sectional view thereof with portions left in elevation to clearly illustrate the relation of the several parts.

Fig. 3, is a plan view of the deflector.

Fig. 4, is a sectional view thereof.

Fig. 5, is a plan view of the outer cap.

Fig. 6, is a sectional View thereof.

Fig. 7, is a plan view of the inner cap.

Fig. 8, is a sectional view thereof.

Fig. 9, is a plan view of the burner hood.

Fig. 10, is a fragmentary sectional view thereof.

Fig. 11, is a sectional view of the burner hood and component parts, a portion of the burner .hood being broken away illustrating the assembly of the parts shown in Figs. 3 to inclusive.

Fig. 12, is a plan view of a perforated ring.

Fig. 13, is a side elevation thereof.

Fig. 14, is an edge or plan view of an imperforate ring used in connection with the perforate ring shown in Fig. 12.

Fig. 15, is a side elevation of Fig. 14.

In carrying out my invention as herein embodied, 16 represents a heating or lighting appliance particularly shown as an oil "ing stove including a body 17, cover 18 Serial No. 46,758.

and heating drum 19. In the body 17 is fitted an oil reservoir or container 20 provided with the usual tubular wick holding members 21 which are of two different diameters arranged one within the other and between these is the wick 22.

On the top or cover 18, which is provided with an opening for registration with the burner elements, is mounted a ring or plate 23 having holes 24 for the reception of suitable fastening devices such as bolts whereby said plate or ring is securely fastened to the stove member and this plate has a ring 25 surrounding the opening 26 through the plate 23 and on top of this ring 25 rests the controller plate 27 secured to the plate 23 by bolts 28 or their equivalent and said controller plate is provided with any desirable number of perforations 29 whereby air may pass into the combustion chamber within the heating drum and mix with the flame in proper proportions for producing the best possible combustion. This construction has been found to control the flame so that it burns in a steady condition without rise or fall unless regulated by the wick. It is to be understood that the plate 23 may be perforate or imperforate and the inner edge of said plate 23 is preferably beveled inward as indicated at 30, Fig. 2.

The reference numeral 31 represents the burner hood which is provided with perforations 32 around the sides thereof and other perforations 33 in the top to allow air to pass upward into the inner cap 34 in the form of an inverted cup thereby providing a top wall 35 which is preferably depressed and this top wall is perforated as at 36. About the inner cap is an outer cap 37 the lower edge of which rests upon the outwardly projecting flange 38 of the inner cap and said outer cap is also in the form of an inverted cup with perforations 39 around the sides thereof while its top wall 40 is preferably imperforate. On top of the outer cap is an arcuate deflector 41 which may be provided with perforations 42. The Cape and deflector are held upon the burner hood by a bolt 43 having nuts 44 thereon at least one on each side of the top of the burner hood so that the bolt may be held in different adjusted positions while another nut or nuts 45 are placed on said bolt to support the inner cap and through the latter the outer cap and deflector and said caps and deflector are held against displacement Lil) by a nut 46 on the upper end of said bolt 43.

\Vithin the air space in the body of the appliance and surrounding the wick holding members or cylinder carried by the oil reser voir is a perforated frusto-conical ring 47, the perforations being shown at 48 in Figs. 12 and 13 and surrounding this is another similar shaped imperforate ring 49 and these two rings form a mixer so that the air will be mixed with the flame as it passes upward through the air spaces.

The illustrations forming a part of this specification would indicate that the parts are made of sheet metal but it is to be understood that I am not limited to any particular material from which these parts are to be made nor the manner of producing them as they niiay be stamped, drawn, cast or otherwise produced' From the foregoing description it will be particularly noted that as the air passes upward through the body of the appliance or through the cylinder of the burner it will be deflected by the several elements and caused to mix with the flame so that said lame may be under perfect control at all times and when in use practically perfect combustion is produced so that there will he more heat and light without odor or soot with a C()l1Sl(lG1'21l)l0 saving in the consumption of fuel. Further a very long or short flame can he used without smoke or odor as is often the case with stoves of this class in general use.

It is to be particularly noted that the lower end of the inner cap 3% is spaced from the top of the burner hood and therefore will admit air to the inner cap in addition to that which passes up through the burner hood and then caused to flow around between the inner and outer aps and out of the perforations 39 in said outer cap 50 as to combine or mix with the flame in producing better combustion. Some of this as Well as other air within the l'ieating drum Will flow around the deflector ll and be deflected into the upper portion of the flame While another portion of the air will pass through the perforations in the deflector and mix with Of course I do not wish to be limited to V the exact details of construction as herein shown as these may be varied within the limits of the appended claims Without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. An air distributor comprising, in combination, a perforated burner hood, an inner cap having perforated top wall, a flange at its lower end, an outer cap having perforated side walls, and an imperforate top surrounding the inner cap and resting upon its flange, an arcuate perforated deflector above the outer cap, and means to fasten the parts together whereby the inner cap will be spaced from the burner hood.

2. An air distributor comprising two concentric caps, the inner one having perforations in its top and the outer one perforations in its sides, an arcuate deflector, and means to fasten said parts together and to a burner hood with the lower end of the inner cap in spaced relation to the top of said burner hood.

3. An air distributor comprising a plate for attachment to the top of an oil or gas burning appliance, said plate having a central opening, a ring on said plate surrounding the opening, a perforated plate resting on said ring and having a central opening for registration with the burner of the appliance, a perforated ring surrounding the wick cylinder of the appliance, an imperforate similarly shaped ring surrounding the first named ring, an inner inverted cup shaped cap having erforations in its top wall, an outer cap coacting with the inner cap and having perforations in its side walls, an arcuate deflector above the outer cap, and means to fasten said caps and deflector on the burner hood of the appliance.

In testimony whereof, I have hereunto aflixed my signature.

SAMUEL HEATH.
